Technical field
The present invention relates to a kind of Mineral Classification sorting unit and method thereof, particularly a kind of pulsation swash plate strengthening classifying and sorting device and method thereof.
Background technology
The operation that material separates with density variation is sorting, and the operation be separated with particle size differences is classification, and in mineral manufacture field, fine fraction mineral classification and sorting is study hotspot always.At present, the equipment for fine particle stage material classification and sorting has hydraulic classification swirler, spiral and TBS etc.
Traditional equipment can carry out classification or sorting to material, but, due to material feature and the structural limitation of equipment own, make classification and sorting effect unsatisfactory, the requirement of mineral high accuracy sorting can not be met, waste is produced to resource.Spiral sharpness of separation is low and floor space is large; The fluidisation water speed of TBS separator can not exceed material termin al velocity, therefore its treating capacity is little.Thus, equipment innovated and transform and just seem particularly urgent.
Integrate, legacy equipment has the following disadvantages: 1. sorting classifying effect is undesirable; 2. treating capacity is low; 3. equipment performance is single, can only carry out sorting or classification.
Summary of the invention
The object of the invention is to provide the pulsation swash plate that a kind for the treatment of capacity is large, efficiency is high to strengthen classifying and sorting device and method thereof, solve legacy equipment to the problem of Mineral Classification sorting deficiency.
The object of the present invention is achieved like this: pulsation swash plate strengthening classifying and sorting device, is made up of vertical cell body and inclination cell body two parts; Described vertical cell body upper end is connected to inclination cell body, arranges parallel oblique plate in inclination cell body, and inclination cell body top is provided with overflow launder; In the middle part of vertical cell body, feeding mouth is set; Be provided with the cloth stream plate communicated with external water inlet pipe bottom vertical cell body, its center is provided with the underflow discharge gate of subsidiary flow control valve.
Preferably, described vertical cell body top is connected to the different inclination cell body of both direction, makes whole device in " Y " type structure.
Preferably, in the parallel draw-in groove being applied in inclination cell body of each hang plate described, quantity can adjust.
Preferably, be hollow bottom described hang plate, surface distributed micropore, and side has circular hole and is connected with the clear water pore on inclination cell body.
Preferably, described underflow discharge gate is with flow control valve, and valve opening is by PID automatic controlling system.
Preferably, described PID automatic control system is by PID control instrument, and the in succession pressure sensor be arranged on vertical cell body and the flow control valve being located at underflow discharge mouth formation.
Classification and sorting method: fluidisation water is moved upward through cloth stream plate access to plant by bottom inlet channel, material is fed by the feeding mouth in the middle part of vertical cell body, move downward in vertical channel, to meet generation fluidization with current, and ramp way is entered under hydrotransport effect, classification and sorting is carried out between hang plate, the particle that density is little or granularity is little moves upward along ramp way and enters overflow, the particles settling that density is large or granularity is large to hang plate surface and slide to bottom hang plate, be subject to the panting action of additional clear water, the less material of a part floats again, stay in inclination cell body and continue classification and sorting, small part material turns back in vertical cell body, final underflow controls to discharge from underflow discharge mouth by flow control valve.
Beneficial effect, owing to have employed such scheme, classification and sorting method, utilizes the fluidization of vertical channel and the invigoration effect of tipper simultaneously, increases fluidizing velocity, increases treating capacity; Can make to feed the terminal velocity that fluidisation water speed exceeds material; Hang plate in inclination cell body, can produce shear action to material, improve stock grading, and then improves the disposal ability of device, improves sorting classifying effect, improves classification and sorting efficiency.
1, the present invention arranges the inclination cell body of two different directions on vertical cell body.Make to enter from vertical cell body in inclination cell body by sorting material, larger fluidizing velocity can be obtained, before breaking through, fluidizing velocity is lower than the restriction of material termin al velocity, makes material can carry out sorting under higher fluidisation water speed, improves the treating capacity of device.
2, when material flows in inclination cell body, density is large, the material that granularity is large to sink to fast on hang plate and slides to bottom hang plate, be subject to the panting action of external adding water, wherein the less particle of a part floats again, stays in inclination cell body and carries out classification and sorting, and the material turned back in vertical cell body is reduced, keep the stable of bed density, improve separating effect.
3, the hang plate arranged in inclination cell body can produce shear action to material, realizes the classification to material.Hang plate inserts in the draw-in groove of inclination cell body, convenient operation, changes quantity and the distance between plates of hang plate, thus obtain different grading effects.
4, PID automatic control system can strengthen the stable of bed density further, ensures higher sharpness of separation, reduces human factor and the impact of pan feeding fluctuation on separating effect.
5, the present invention adds inclination cell body on vertical cell body, and arranges adjustable hang plate in inclination cell body, and the quantity of adjustment hang plate and distance between plates, both improve unit capacity, reduces floor space, improve again sorting classifying effect.
